ResearchAlmost everything is made up of atoms. Actually, the stuff that is not made up of atoms is a bigger share of the Universe but most of the stuff I care about is made of atoms. Things like galaxies, stars, planets, mountains, oranges, cows, water, people, ... Anyway, at the center of atoms there are atomic nuclei and those are made of particles called neutrons and protons. Those, by their turn, are made of other particles called quarks and gluons. My main research interest it to understand how quark and gluons behave: why don't they ever leave the protons and neutrons? how their motion generates the force between protons and neutrons that keep atomic nuclei together? what happens when protons and neutrons are squeezed into a small volume? For this I use all the tools at my disposal, from some beautiful mathematics to phenomenological models and large scale numerical analysis. A flavor of these efforts is given by the review articles and talks below.
A recent colloquium about the calculations of nuclear forces from first principles.
A review describing the use of effective field theories to nuclear physics.
Two for the price of one: a talk about cold polarized atoms in traps and a mechanism for the cooling of nuetron stars.
